Disregard the numbers printed on the switch
When setting the base address, refer to the numbers printed in white on the printed circuit board.
Individual / simultaneous transfer jumper
The analog outputs can be jumpered so that new output data are held until all DAC registers have been loaded
with new data. The new data updates the voltage outputs when any of the board addresses are read.
A single jumper controls whether all of the DACs are either simultaneously transferred on a read ( XFER ), or
individually updated when the control register is written ( UPDATE ). Figure 3 shows the jumper block
configured for each update mode.

Figure 3. Individual / simultaneous update jumper
Use this feature to maintain a zero volt output after power-up by loading all DAC registers with mid-scale
values (8000h) and then updating.
